Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D stereoscopic image technologies based on binocular disparity cause accommodation-convergence mismatch, leading to visual fatigue and discomfort, as they struggle to provide a natural 3D stereoscopic effect, limiting their ability to represent immersive and interactive hologram-like experiences.
Innovation Solution
An expanded 3D stereoscopic image display system that utilizes multiple heterogeneous or homogeneous display devices, including standing, flexible, portable, and wearable devices, to create a unified stereoscopic image space, controlled by a unit that sets and shares 3D image display spaces and distributes content based on user line of vision information, allowing for the fusion of multiple 3D images into a single immersive space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If binocular disparity effect is used to create 3D stereoscopic images, then a 3D stereoscopic effect is achieved, but accommodation-convergence mismatch occurs causing visual fatigue
Solution Approach 1:
The patent combines multiple display devices (TV, monitor, mobile device, wearable device) into a unified 3D stereoscopic display system that shares a common virtual display space. This integration allows the system to maintain accurate accommodation-convergence matching across different devices by coordinating their display parameters through a control unit, thereby reducing visual fatigue while preserving the 3D effect.
Solution Approach 2:
The control unit implements universal control across heterogeneous display devices, enabling them to function together as a single coordinated system. By managing display parameters (brightness, contrast, refresh rate, 3D depth) across multiple device types, the system achieves consistent accommodation-convergence matching that prevents visual fatigue while maintaining reliable 3D stereoscopic presentation.
2Volume of stationary object
If multiple display devices are used to expand 3D display space, then immersive experience is improved, but system complexity increases
Solution Approach 1:
The control unit serves as an intermediary that manages communication and coordination between multiple heterogeneous display devices. It handles device discovery, capability matching, and parameter synchronization, thereby simplifying the system architecture and reducing complexity while enabling expanded 3D display space through multiple devices.
Solution Approach 2:
The system segments the 3D display function across multiple independent devices, each operating within its own capabilities while contributing to a unified virtual display space. The control unit divides content rendering and parameter control across devices based on their individual characteristics, managing complexity through functional segmentation.
3Productivity
If display parameters are optimized for each device independently, then device performance is maximized, but coordination between devices deteriorates
Solution Approach 1:
The control unit dynamically adjusts display parameters (brightness, contrast, refresh rate, 3D depth) across multiple devices based on their individual capabilities and the current viewing conditions. It optimizes each device's performance parameters while maintaining coordinated operation through real-time parameter synchronization, thereby achieving both high device performance and stable system coordination.
Solution Approach 2:
The system implements dynamic parameter adjustment where display characteristics are continuously optimized based on device capabilities, content type, and viewing conditions. The control unit adapts synchronization settings and display parameters in real-time, maintaining both individual device performance and overall system coordination through dynamic rather than static configuration.
